With the increasing availability of unmanned aircraft systems, their usage for search and rescue is close at hand. Especially in the maritime context, aerial support can yield significant benefits. This article proposes and evaluates the concept of combining multiple cellular networks for highly reliable communication with those aircraft systems. The proposed approach is experimentally validated in several unprecedented large-scale experiments in the maritime context. It is found that in this scenario, conventional methods do not suffice for reliable connectivity to the aircraft with significantly varying overall availabilities between 68% and 97%. The underlying work, however, overcomes the limitations of single-link connectivity by providing availability of up to 99.8% in the analyzed scenarios. Therefore, the approach and the experimental data presented in this work yield a solid contribution to search and rescue drones. All results and flight recording data sets are published along with this article to enable future related work and studies, external reproduction, and validation of the underlying results and findings.

Explanatory Information

Currently, the existing approaches to geodetic support for the design, survey, construction and reconstruction of buildings and structures do not fully meet the needs of the construction industry. Digital large scale topographic plans do not fully reflect the situation on the construction site. In this regard, to supplement digital engineering and topographic plans with information obtained using the survey materials of unmanned aircraft systems (UAS) is proposed. The article discusses the possibilities of obtaining and processing the materials of surveying with UAS at low altitudes, using the example of the construction of a new metro station in Novosibirsk. The DJI Phantom 4 PRO quadrocopter was used as a UAS. The accuracy of the obtained orthophotoplan is sufficiently suitable as explanatory information for the digital engineering and topographic plan of the object under study.

Awareness System

ABSTRACTA novel statistical model is presented to quantify situation awareness in the operation of small civilian Unmanned Aircraft Systems (UAS). Today, the vast majority of small Unmanned Aircraft Systems (UAS) operation takes place under Visual Line of Sight (VLOS) of a human operator, who is wholly responsible for the safety of the flight. As operation begins to move to Beyond Visual Line of Sight (BVLOS), it is likely that this responsibility will become shared between operator and the increasingly autonomous UAS itself. Before we seek to quantify the safety of such a system, it is beneficial to analyse the safety of existing Visual Line of Sight (VLOS) operations to provide a target level of safety. Prior to considering any on-board decision making, it is essential to ensure that the artificial situation awareness system of a UAS in Beyond Visual Line of Sight (BVLOS) is at least as good as awareness of a human operator. The paper provides a probabilistic theory and model for the high-level abstractions of situation awareness to guide future assessment of BVLOS operations.
